Embodiment Construction

[0046] figure 1 A first step in the embodiment shown in is the recording of the ACQ raw data set by means of the medical imaging device 200 using the measurement protocol 300 . The medical imaging device 200 is a magnetic resonance tomography device in the present exemplary embodiment. Alternatively, however, it can also be, for example, a computed tomography system or a positron emission tomography system. The way in which the ACQ raw data records are recorded by means of the medical imaging system 200 is known from the prior art and will therefore not be explained in detail here. Measurement protocol 300 here includes parameters 301 , 302 , 303 which are designed for recording an ACQ raw data set at medical imaging device 200 . Furthermore, the measurement protocol includes, for example, a unique identifier 301 of the measurement protocol, the name of the examined body part 302 and the slice thickness 303 of the tomographic record. Furthermore, the measurement protocol ca...

Abstract

A raw data set is acquired using a scan protocol via an imaging medical device. In an embodiment of a method, the raw data set and the scan protocol are transmitted from the medical device to a reconstruction unit. Furthermore, an at least two-dimensional image data set is calculated from the raw data set via the reconstruction unit. Furthermore, a display parameter is fetched via the reconstruction unit, the display parameter being assigned to the scan protocol and the display parameter defining a first projection method for the image data set. Furthermore, the image data set and the displayparameter are transmitted from the reconstruction unit to a display unit, the reconstruction unit and the display unit being spatially separate. Furthermore, a first projection data set is determinedby applying the first projection method to the image data set via the display unit.

Description

technical field [0001] The invention relates to a method for determining projection data sets, a projection determination system, a computer program product and a computer-readable storage medium. Background technique [0002] In medical imaging, in particular tomographic medical imaging, raw data recorded by an imaging device are usually converted into image data by a reconstruction unit and stored in a standard format. This image data can then be viewed and analyzed by the user. [0003] Different representations of the examined target volume are used here for different medical questions. Especially for special exams, such as angiography or magnetic resonance cholangiopancreatography ("MR-CP" for short), the image data must be reformatted or otherwise displayed before viewing. Among other things, multiplanar reconstruction ("MPR" for short), maximum intensity projection ("MIP" for short) or subtraction are used for this purpose. [0004] It is known to implement differe...
